STUMF-PULLER.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed August 5, 1910. Serial No. 575,720.

T o all whom it may concern: y

Be it known that I, ABRAHAM T. FAIREY, a citizen of the United States ofAmerica, residing at Laceola, in the county of Madison and State ofTexas, have invented new and useful Improvements in Stump-Fullers, ofwhich the following is a specification.

This invention relates to stump paliers, and the object of the inventionis to provide improved extracting mechanism embodying a lifting memberand gripping members for gripping engagement with the stump and'operable to elevate the stump on rotation in one direction of thelifting element.

A still further object of the invention is to provide improved means formoving the said gripping members into and out of engagement with thestump.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several viewsz-Figure 1 is a detail perspective view of my improved stump puller.Fig. 2 is a vertical section therethrough.

The stump puller consists preferably of a portable structure comprisinga pair of suitably spaced runners 1 from each of which arises a pair ofstandards 2.y The standards 2 are connected at their upper ends by bracebars 3 on which is mounted a head 4. The standards 2 which arediametrically opposite are connected with each other by braces 5. Therunners have mounted thereon suitable wheels 6 and at the front, eachrunner is provided with a draft attachment 7 The head 4 of the structuredescribed above is provided with a central passage 8 through whichextends the depending portion of a bearing 9. This bearing is formedwith an exterior groove 10 which is located immediately beneath the head4. A split washer 11 is secured to the underside of the head and itextends into the groove 10 so as to hold the bearing 9 againstaccidental displacement. The provision of the washer 411 is such thatwhen the bearing becomes worn it may be removed and replaced by a newone at a minimum cost. The upper surface of the bearing is formed toprovide an annular groove 12 which is disposed immediately beneath asimilar groove 13 in the bearing 14. Antifriction bodies 15 are arrangedin the raceway formed by the grooves 12 and 13 of the just describedbearings. The bearing 14 is formed with a depending portion 16 whichextends through a correspondingly formed passage in the gearing 9. Thebearing 14 is formed to provide a vertically disposed threaded passage17 which receives a screw shaft 18.

The shaft 1S forms a lifting element of my improved extracting means andat the lower end the said shaft is provided with a rotatably mountedhead 19 which has mounted thereon a plurality ofy hook-like grippingmembers 20. These gripping members are designed for engagement with thestump as will be understood. The shaft is formed to provide a stopshoulder 21 on which the head 19 rests.

The bearing 14 is formed to provide a groove 26 in which theintermediate portion of the sweep member 27 is seated. The sweep memberis provided with the oppositely extending arms 28 to which the draftanimal may be attached when it is desired to rotate the screw shaft 1S.The fastening devices 19 extend through the intermediate portion of thesweep member and into the bearing 14.

In operation of the stump puller herein described and shown, the runnersstraddle the stump to be extracted and the screw shaft 1S is adjusted soas to move the shaft toward the stump and in position to permit thehoololike members 20 to be engaged therewith after the screw shaft hasbeen adj usted to this position it is rotated to move the same away fromthe stump, whereupon, the elements 2() will be moved into grippingengagement therewith.

I claim 1. In a stump puller, a portable support, a bearing memberextending through the support and provided on the underside of thesupport with an exteriorly grooved portion, a removable plate engagedwith the support and extending into the groove of the said bearingmember, an actuating member supported by the bearing member and having athreaded passage therein, a screw shaft extending through the passage ofthe said actuating member, and stump gripping elements supported by thesaid shaft.

2. In a stump puller, a portable support, a bearing member extendingthrough the support and provided on the underside of the support with anexteriorly grooved portion, a removable plate engaged with the supportand extending into the groove of the said bearing member7 an actuatingmember In testimony whereof I axr my signature supported by the bearmgmember and hav- 1n presence of tWo Witnesses.
